摘要 文章提出一种新型的光载波抑制-差分相移键控(OCS-DPSK)调制格式,可以实现光载无线(RoF)系统的3个关键功能:分发下行RoF信号、产生远端本振信号和上行数据的重调制,从而实现成本最优的RoF接入网络。文章作者实验演示了基于单个单臂马赫-曾德调制器产生OCS-DPSK控调制格式的全双工RoF传输系统。 This article demonstrates that Optical Carrier Suppressed-Differential Phase-Shift Keying (OCS-DPSK) modulation format can be used to realize three key functions in Radio over Fiber (RoF) system: delivering downlink RoF signals, generating remote Local Oscillator (LO) signal, and re-modulating uplink signal. Therefore, the best-cost RoF access network could be realized. The full-duplex ROF system based on one single-drive Mach-Zehnder Modulator (MZM) to generate OCS-DPSK is introduced.
